Yes, well, that may be true, but obviously your post has brought some attention.
This forum can be described as conservative, but on the other hand on this forum rests experience of hundreds of safaris done from clients and outfitters perspective. That has some weight.
In general, this is new caliber with which most of us dont have any experience with.
Judging simply from ballistic table, and having 3 safaris done, I have some doubts.
For example, a realistic situation of shooting standing from stick, distance about 200 yards, at large animal such as eland, kudu, or similar (name the animal), which is standing at awkward angle, half covered by the bush, with wide intermittent changing side wind, this is not unusual situation and can be expected.
In such situation if a shot is taken with marginal bullet by energy and velocity, it could mean, wounding and tracking.
Wounding also means, full payment of trophy fee, whether the game is recovered or not.
Those are risks involved. And our small forum community does not take this lightly.
Now, some arguable credits.
I hunt everything from fox to deer and boar, or african game.
I was trying hard to understand the terminal ballistics and to find perfect bullet that can do it all. I did not find. Finally I came to conclusion, that bullet must be chosen for specific type of hunt.
So, I have read quite a few books on subject of ballistics, in parallel with my personal hunting experience.
But what I first found out, hunting bullet terminal performance, is not something to find in any scientific approach in the books that i could find.
What you can find are practical manuals, such as Robertsons Perfect shot 2.
It iis based on experience and deep understanding of animal anatomy. This is really informative publication
Then, I turned to forensic ballistics, and took a look, in few books. Those books covered the subject in more details the arguable effect of hydrodynamic shok. But, again, majority of sampling was done on various FMJ bullet wounds, with casualties of war. (this is not hunting, nor hunting bullet performance)
So, although it gave me some idea about velocity as a factor in terminal ballistics (potentially but not always causing hydrodynamic shok), I again did not find the answer (mathematical formula or definition) what a perfect hunting all around bullet would be.
But, in one of the books I remember, there were few lines saying that a bullet that spins faster, has potential to be more lethal when compared to same bullet of slower spin. (or at least. there are indications to support that thesis)
As far as theoretical and scientific approach, it seams that ammunition factories are doing the most thorough research about effectiveness of hunting bullet, but exact findings are not in public domain, except as part of advertising.
From this source and other, what one can conclude, expansion of bullet is the factor of velocity on impact, bullet construction, and materials used. (not the function of bullet spin).
Which brings us to the beginning of this discussion.
Experience teaches us of what works and what works not.
All in all, make thorough research of where you will be hunting, hunting area and country, and make due diligence of outfitter. Discuss all details with PH, follow advice.
Most probably South Africa will be the place first to look for.
2025!
